IMPROVEMENT IN DRA FT-EQUALIZERS.

Specification forming part of Letters Patent No. 168.699, dated October 11, 1875 application filed July 31, 1875. i

other horse without pulling the cultivator out I of a straight line.

Draft-equalizers have been made in various forms heretofore, but none, to my knowledge, which combines so efi'ectually all the qualities desired in such a device without at the same time increasing the cost of the machine.

The machine is illustrated more in detail in the vertical views, Figure l and Fig. 2, and in the plan view, Fig. 3.

The casting A forms an arch, straddling the row of corn in the usual manner; but it has formed on it the arms B B, into which the grooved pulleys O G are inserted. The pipe D may also form a part of the same casting, leaving between it and the top E of the arch just sufficient room to insert the tongue F. The axles G G have, between the casting A and the wheels K K, grooved pulleys I 1, under which, and over the pulleys G G, and

through the pipe D, passes the rope or chain J connecting forward with the hanging levers L L, hinged to the cross-beam M. To these hangers L L are hitched the horses, at any point desired, there being a number of holes through the hangers, so that the operator may choose the right place,according to the strength of each respective horse. The plow-beams (not shown in the drawing) are attached to the axles G G, in the usual manner. The object of the pipe D is to prevent the lines from coming in contact with the rope or chain J, which might interfere with the free working of the machine.

It will thus be seen that by means of the hangin g levers L L the draft can be so nearly equalized that the rope or chain J will easily balance whatever difference may arise between the two horses, the sweep of the levers L L being very long, so that the workman will not be annoyed by the machine occasionally jerkin g sidewise, as .other machines sometimes do,
